Allen-Bradley 800MR-N49 Push Button Switch

Allen-Bradley 800MR-N49 is a yellow, non-illuminated round flush-head push-button from Rockwell Automation's 800MR series, engineered for panel mounting in industrial control panels and equipment; its low-profile flush head provides a smooth, snag-resistant actuation surface and a clearly visible yellow actuator. Within the 800MR family, the N49 suffix designates the yellow finish and flush-head configuration, and this variant is documented as a push-button component that is compatible with other 800MR operators and caps, enabling straightforward replacement in existing installations. Being non-illuminated, the N49 relies on ambient lighting and printed panel labeling rather than built-in illumination, which can simplify maintenance in harsh environments and reduce the risk of lighting failures while preserving tactile feedback. Typical applications include machine controls, conveyors, presses, and general automation panels where a visually distinct yellow push-button is used to initiate or stop a function, with the color providing quick at-a-glance identification in complex control schematics.
